[FEATURE] Resizable query section

[msfroh]

Is your feature request related to a problem?

Yes. When editing a query, the DSL can get pretty verbose. The query box seems to be sized for about 8 lines of query text.

Following the JSON convention of putting one property on each line and closing curly braces on their own line, it's really hard to fit a non-trivial query on screen, meaning I need to scroll.

What solution would you like?

I would like the query boxes to be expandable vertically. I think we should add a handlebar to adjust the space allocated to queries versus results.

What alternatives have you considered?

1. Could just make the query boxes bigger (but still fixed). I don't think this is the right solution, though, because once I'm done editing the queries, I do want to devote more screen real estate to the results.
2. Maybe the query boxes could be large, but "behind" the results. When one query box or the other has focus, they could be brought to the front and moved back when focus is lost.

Do you have any additional context?

The following screenshot shows the problem. The query on the left is 9 lines, while the one on the right is 22 lines.
